WATCH: Flea jams with Koko the Gorilla

Red Hot Chili Peppers bassist Flea was at the Gorilla Foundation in Woodside, California yesterday and gave a music lesson to an adorable yet probably very difficult pupil: Koko the Gorilla!

“This is just the greatest thing that could ever happen. This is the day that I will never forget in my life,” Flea said.

“One of Koko’s favorite musicians, Flea from the Red Hot Chili Peppers came to visit,” the Gorilla Foundation wrote on their website. “Koko was thrilled by the mellow sounds and a jamming session followed with Koko strumming on Flea’s bass!”

The foundation is also looking forward to “future collaborations” between Flea and Koko.
